Welding two pieces of stainless steel by spot welding, which spot welder is the best? AC, DC?What is an inverter type medium frequency spot welder?
Ordinary argon welder is OK
There are many welding methods, such as gas shielded welding, argon arc welding, electrode welding and submerged arc welding.In accordance with your needs, small quantities, you can use gas welding, welding rod arc welding. High quality requirements can be achieved by argon arc welding. The workpiece is large enough for submerged arc welding.Welding machine is to use the positive and negative poles in an instant short circuit when the high temperature arc to melt welding electrode on the solder and welding material, so that the combination of the purpose of contact. The structure is very simple, that is, a high-power transformer. Welder according to the type of power output can be divided into two kinds, one is AC power supply, and the other is direct current. They use the principle of the inductor, inductance voltage will produce a huge change in the on and off, resulting in high voltage arc when sudden short-circuit the use of positive and negative poles to melt the solder wire, to allow them to reach the purpose of atomic binding.
You see how thick stainless steel and stainless steel, AC welder / welder / welding inverter welding can be done, see you on the requirements of the degree of the welding quality is high. If you require solder joint appearance, stable welding, welding inverter can be used only if required, meanwhile, a high degree of oxidation of the solder joint is not required. AC welder / welder can be suitable for you.
