Prototype Surface Finishing of Welding
- Apr 13, 2018 -
Welding, also known as splicing, is a manufacturing process and technique for joining metal or other thermoplastic materials (such as plastics) with heat, high temperature, or high pressure.
Here are two commonly used welding methods in the rapid prototyping industry.
1. Laser welding
Laser welding is a type of high-energy beam welding, whihc equipment is generally used for welding, and it is a welding method using a high-power coherent monochromatic photon flux focused laser beam as a heat source for welding.
This welding method usually has continuous power laser welding and pulsed power laser welding. The advantage of laser welding is that it does not need to be conducted in a vacuum and can perform precise energy control, thus enabling the welding of precision devices. It can be applied to many metals, in particular to the welding of difficult-to-weld metals and dissimilar metals. At present,it has been widely used for mold repair.
2. Argon arc welding
Argon arc welding is a type of arc welding. It mainly uses the arc that is continuously fed between the welding wire and the workpiece as a heat source, and the arc is sprayed by the torch nozzle to protect the arc.
At present, argon arc welding is a common method and can be applied to most major metals including carbon steel and alloy steel. MIG welding is applicable to stainless steel, aluminum, magnesium, copper, titanium, zirconium, and nickel alloys. Due to its low price, it is widely used for mold repair. However, welding heat has a large area of impact, large solder joints, etc. Precision mold repair has been gradually replaced by laser welding.
