Laser Welding Machine
The laser welding machine is capable of precise welding of almost any kind of metal and their alloys. Its advantages over the conventional welding techniques include fine finish, fast process, high depth-width radio, post-process free, small heat affected zone. Spot welding and seam welding are two very popular methods used for sheet metal parts.
- Spot welding is primarily used for joining parts that normally upto 3 mm (0.125 in) thickness.
- Spot-weld diameters range from 3 mm to 12.5 mm (0.125 to 0.5 in) in diameter.
Features
- Large range welding, surface welding ,air protection
- High speed, handsome welding point
- Small focus poin, high precision
- Small heating area, little distortion
Manufacturing Considerations
Thickness of the parts to be welded should be equal or the ratio of thicknesses should be less than 3:1. Spacing of welds
- Min. Weld to weld spacing = 10 x Stock thickness.
- Center of weld to edge distance = 2 x weld diameter, minimum.
- Weld to form distance = Bend Radius + 1 weld diameter, minimum.
Adequate access for spot welding should be considered. Small flanges in U channels for example may restrict the electrode from entering the part.
Flat surfaces are easier to spot weld due to easy access. Multiple bends impose access restrictions, and special fixtures may have to be designed to handle the parts, if access is not a problem.
Prior to finishing, the spot welds have to be sanded or ground to blend the welds with the rest of the surface. It is best to choose the same spot weld size, to minimize setups and increase throughput.
Plating of spot welded assemblies can cause problems when the sheet metal is overlapped. This can cause plating salts to be trapped-requiring special cleaning, or potential long-term corrosion problems. By carefully designing the assembly to allow easy draining of plating solutions this can be avoided.
