Welding Systems for Precision Industrial Manufacturing
Keje Electric Company is a leading laser Laser Welding Machine Supplier in India Keje Electric Company is a laser welding machine manufacturer in India building and supplying fibre laser and Nd: laser welding systems for automotive components, electronics manufacturing, medical devices, EV battery production, and precision fabrication. Our systems are designed and commissioned from our MIDC Pimpri facility in Pune and installed at client plants across India. Laser welding is not a replacement for all conventional welding. It is the right choice when the component demands weld precision that TIG and MIG cannot deliver—thin-gauge materials below 1mm, heat-sensitive assemblies, stainless steel cosmetic welds, and micro-welding on electronic or medical components. If your application falls into this category, laser welding is worth a serious look. If it does not, we will tell you that and recommend a better fit from our product range. smarter choice. As a trusted laser welding machine supplier in India and experienced laser welding solutions provider in India, we deliver systems that ensure clean welds, deep penetration, and unmatched accuracy.
Laser Welding Systems Built for Precision and Efficiency
A laser welding machine focuses a high-energy laser beam onto a small spot — typically 0.2mm to 1.5mm diameter — to melt and fuse metal with minimal heat spreading into the surrounding material. The result is a narrow, deep weld with a heat-affected zone (HAZ) far smaller than any arc welding process. This is why laser welding is used for applications where distortion is unacceptable: medical implants, battery pouch connections, thin-wall stainless assemblies, and precision sensor housings. Two laser types dominate industrial production. Fiber lasers use an optical fibre doped with rare earth elements (typically ytterbium) as the gain medium. They are compact, efficient, and the current industry standard for most new installations — particularly in automotive and EV applications. lasers use a neodymium-doped crystal and are well-established in jewelry, medical device, and precision tooling applications where pulsed welding at very low energy per pulse is needed. As a laser welding machine manufacturer in India, we supply and integrate both types based on your material, thickness, and production requirement. We do not push one platform over another — the right laser type is determined by your component drawing.
Laser Welding Solutions
We supply laser welding systems in three integration levels depending on your production requirement — from bench-top manual systems for tool rooms and prototype production, to fully enclosed automated cells for high-volume manufacturing lines:
Features of Our Laser Welding Machines
Laser Types Available: Fiber laser (CW and pulsed) and pulsed laser systems — selected based on material, thickness, and required energy per pulse.
Power Range: 100W to 6000W depending on application. Battery tab welding at 300W to 1000W. Automotive structural welding at 2000W to 6000W.
Beam Quality (M²): Fiber lasers: M² < 1.1 (near-perfect Gaussian beam). M² 10 to 25. Better beam quality gives smaller spot diameter and cleaner weld profile.
Low Heat-Affected Zone: HAZ width 0.1mm to 0.5mm depending on parameters — compared to 1mm to 5mm for TIG on the same material. Less distortion, less post-weld correction.
Weld Speed: 1 m/min to 20 m/min depending on material thickness and joint type. Significantly faster than TIG on materials below 3mm.
Control Systems: CNC and PLC-based parameter control. Weld energy, pulse duration, peak power, and focal position all digitally controlled and logged per weld for traceability.
Automation Options: Manual bench systems, 3-axis CNC gantry systems, robotic arm-mounted laser heads, and inline conveyor-integrated welding cells.
Monitoring and Quality Assurance: Real-time photodiode monitoring for weld pool radiation. Optional inline seam tracking and vision inspection for automated lines.
Applications of Laser Welding Machines
Our laser welding solutions are widely used across industries in India, especially where precision and quality are critical.
-
Automotive Industry: Transmission parts, gear assemblies, sensor housings, and airbag components. Thin-wall stainless and aluminium assemblies requiring zero distortion. Automotive is the largest market for fiber laser welding in India.
-
Electronics Manufacturing: Battery tab welding, cell-to-busbar connections, and battery pack sealing. Copper and nickel tabs welded with pulsed fiber laser at 300W to 800W. One of the fastest-growing applications in India's manufacturing sector.
-
Medical Device Manufacturing: Connector welding, hermetic sealing of electronic enclosures, and micro-welding of sensor and actuator components below 0.5mm thickness.
-
Jewelry Industry: Surgical instrument welding, implant manufacturing, and medical enclosure sealing. Requires clean weld finish, biocompatible material handling, and traceability documentation.
-
Aerospace Industry: Pulsed Nd: for gold, platinum, and palladium repair and fabrication. Spot welding at 0.1J to 5J per pulse. The original laser welding application — still one of the best use cases for pulsed laser.
-
Sheet Metal Fabrication: Thin-gauge stainless housings, enclosures, and precision assemblies where MIG or TIG would cause warping. Common in instrument panels and food equipment manufacturing.
-
Battery & EV Industry: Titanium and nickel superalloy welding for structural and propulsion components. Strict quality documentation and weld traceability required.
Why Choose Keje Electric as Your Laser Welding Solutions Provider in India
We have been building resistance welding machines — spot, seam, flash butt, and projection — at MIDC Pimpri since our founding. Laser welding is a newer addition to that range. The electrical engineering, control systems, and machine integration knowledge is the same. What is different is the laser source and optics, which we source from established laser manufacturers and integrate with our own mechanical and electrical design. This matters because laser welding failure is usually not a laser failure — it is a fixture problem, a parameter problem, or an operator training problem. Our engineering team has handled all three across our welding machine product range. We know what causes process instability and we design systems to prevent it. As a laser welding machine supplier in India, we cover the full scope: application feasibility assessment, system selection, machine supply, fixture design if needed, installation, parameter optimisation, and operator training. If the application is not suitable for laser welding, we say so and suggest an alternative from our range.Kejje Electric
Frequently Asked Question
What is a laser welding machine used for?
A laser welding machine focuses a high-energy beam onto a small area to melt and fuse metal. The concentrated energy creates a narrow, deep weld with very little heat spreading into the surrounding material. It is used where conventional welding causes too much distortion — thin-gauge materials, heat-sensitive assemblies, cosmetic welds on visible surfaces, and precision components where weld placement tolerance is tighter than TIG or MIG can reliably deliver.
What materials can be laser welded?
Stainless steel, mild steel, galvanised steel, aluminium, copper, titanium, nickel alloys, and most engineering metals. Dissimilar metal combinations — steel to copper for battery contacts, for example — are possible with pulsed laser at controlled energy levels. Gold, platinum, and palladium are welded with pulsed for jewelry and medical applications. Plastics are welded with specific laser types (diode and fiber at specific wavelengths) — this is a separate application we can advise on based on your material.
What are the advantages of laser welding over TIG welding?
Three main differences. Speed — laser welding is 3x to 10x faster than TIG on materials below 3mm. Heat input — laser's heat-affected zone is 0.1mm to 0.5mm versus 1mm to 5mm for TIG on the same material, which means less distortion and less post-weld straightening. Automation compatibility — laser welding heads are easily integrated with CNC gantries and robot arms for fully automated production. TIG is harder to automate because arc stability and wire feeding are more sensitive to position variation. The disadvantage of laser is upfront system cost — it is higher than TIG, which is why the economics only work above a certain production volume or quality requirement.
Do you provide customised laser welding solutions?
Yes. Most laser welding applications need some level of customisation — the fixture holding the component, the motion system (CNC gantry or robot arm), the shielding gas arrangement, and the parameter set are all specific to the material and joint geometry. We assess your component drawing and production volume, select the appropriate laser type and power level, and design the system around your application. We do not sell a standard machine and expect it to work on every job.
Do you supply laser welding machines across India?
Yes. As a laser welding solutions provider in India, we supply and commission systems at client plants nationwide. Installation, parameter setting, and operator training are conducted at your facility by our engineering team. After commissioning, remote diagnostics support is available for control system issues and a 12-month on-site warranty covers hardware faults.
How is weld quality assured in laser welding systems?
At the process level — consistent beam power, stable focal position, controlled travel speed, and correct shielding gas flow. All of these are digitally controlled and logged per weld in our systems. For production lines with quality audit requirements, we integrate inline monitoring: photodiode sensors detect weld pool radiation variations that indicate porosity or lack of fusion before the component leaves the station. For applications requiring destructive testing data during process qualification — weld cross-section, tensile testing — we support this during the commissioning and PPAP phase.
