FAQ

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.

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.

Which is better, TIG welding method and MIG welding method?

TIG welding method and MIG welding method must be MIG better, mainly reflected in1) shaping well2) high efficiency3) TIG can be welded to some limited materials, and sizes, such as large plates, thick platesFrom a practical point of view, TIG welding method is more practical than MIG welding, mainly reflected in1) TIG generally based on the same brand, TIG is cheaper2) the cost of using is also lower3) general TIG is relatively easy to carry4) more popular, more suitable for small batch and spare parts welding.

The difference between MAG welding machine and MIG welding machine

MIG:Metal Inert Gas welding, MIG welding, argon gas, helium (Ar) (He) or a mixed gas, do not react with liquid metal, only isolated from the air, so stable arc combustion, droplet transition smooth, stable, no fierce splash, the most suitable for welding of aluminum, copper, titanium and other non-ferrous metals, can also be used for steel, such as stainless steel, heat-resistant steel welding etc.;MAG:Metal Active Gas welding, metal active gas welding, gas by inert gas and a small amount of oxidizing gases (O2, CO2 or a mixed gas) mixture, without changing or basically does not change the inert gas arc characteristics under the condition of improving arc stability, improve the forming and reduce the radiation intensity of arc weld, welding used in black metal materials.

MIG automatic welding is always broken arc is how ah?

The description of the problem is too vague. What is the phenomenon of arc breaking?Two possibilities:1. current voltage is relatively large, but not to melt the wire too fast, there will be a section of a wire melted, intermittent arc2., feeding wire interruption, arc back to the wire feeder, because the discharge distance is too large, resulting in arcing

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!
