FAQ

What brand of MAG/MIG welding machine good stability high load rate (the main processing non-ferrous metals such as copper and aluminum) and the teacher requested to introduce.
This depends on the actual situation of your company, depending on how much money you intend to buy. I used the equipment has Sweden ESAB, France SAF, Japan OTC, are very good, domestic also write, but the performance is good is not too much! You can choose a few brands by comparison!
MIG automatic welding is always broken arc is how ah?
Two possibilities:1. voltage current is too large, is the wire too fast but not to melt, there will be a section of a wire is melted, and the arc (conductive mouth there is no welding slag sticking often? If so, that's why.)2., feeding wire interruption, arc back to the wire feeder, because the discharge distance is too large, resulting in arcing
Which is better, TIG welding method and MIG welding method?
The former is suitable for welding thin plate, which is suitable for heavy plate and mass production. In many aspects, TIG welding is less limited.
What are the principles of Tandem twin wire welding and monofilament composite pulsed MIG welding?
Tandem uses double wire and double arc welding. The phase difference between two welding pulse current is 180 degrees. This can effectively avoid interference between two over arcs. The utility model has the advantages that the cooling speed of the molten pool is slow, the metallurgy is sufficient, and the mixing of the molten pool is greatly reduced, and the porosity tendency is reduced.Filament compound pulse. It is called "double pulse". This welding is widely used in aluminum alloy welding.
The difference between TIG welding and MIG welding
TIG is a non melting electrode TIG welding, is a manual electric arc welding with argon gas protection, while MIG belongs to inert gas welding consumable electrode, and the TIG is different to manual wire for automatic wire feeding.
The difference between MAG welding machine and MIG welding machine
Active gas shielded arc welding (MIG) can be applied to most of the major metals, including carbon steel and alloy steel.Inert gas shielded welding (MAG) is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. The arc welding can be carried out by using the welding method.
