TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Wear zinc coating first, otherwise it is easy to form inclusion and other defects, and damage the strength of matrix.
