Laser welding is an advanced welding technology that offers various benefits over traditional welding methods. A laser welding machine can precisely weld different types of materials like mild steel, stainless steel, galvanized steel, and aluminum alloys. Here are some key benefits of using a laser welding machine for welding different common materials:

Mild Steel

Mild steel, with low carbon content, is easy to weld using a laser welding machine. Some benefits are:

• Higher strength and integrity of welds due to deep weld penetration and smaller heat affected zones
• Minimal distortion of the welded parts even for thick sections
• Narrow weld seams with good cosmetic finish
• Easy automation of the welding process
• Higher productivity and throughput

Stainless Steel

Stainless steels are difficult to weld using conventional welding methods due to problems like micro-fissuring, intermetallic formation, and porosity. Laser welding solves these issues and offers:

• Minimal heat input reduces cracking and contamination
• Less discoloration of the welded parts near the weld seam
• Better mechanical properties and corrosion resistance of the welds
• Tighter tolerances and precision joints
• Consistent weld seam geometry for automation

Galvanized Steel

The zinc coating on galvanized steel needs to be removed before arc welding but a laser beam can pass through the coating and precisely melt the base metal. This allows:

• No need to remove the zinc coating, saving time and reducing hazards
• Uniform and sound welds with high joint efficiency
• Less unevenness, holes and porosity in the welds
• Less dezincification (loss of zinc coating integrity) near the weld area
• Automatable solution for mass production and assembly lines

Aluminum and Aluminum Alloys

Laser welding machine MS SS galvanized aluminum alloys offers benefits like:

• Prevention of oxidation and hydrogen embrittlement issues
• Less heat affected zone and distortion of the welded parts
• Narrow weld seams and good aesthetic finish
• High joint strength due to deep weld penetration
• Faster process speed and cycle time
• Ease of automating and integrating into production lines

Other Benefits Of

In addition to material-specific benefits, laser welding machines provide the following general advantages:

• Precision – Narrow laser beam allows positioning accuracy of <0.1mm
• Control – Process parameters can be controlled accurately
• Speed – Fast welding speeds of upto 10 m/min can be achieved
• Quality – Minimal porosity and uniform weld seam geometry
• Flexibility – Can weld a variety of materials and thickness
• Ease of automation – Robot mountable laser heads and software for automation
• Cost effectiveness – After initial investment, operating costs are lower
