Thin stainless steel by argon arc welding? [around 0.7]? How to use argon arc welding machine? What is the current size of argon?
Thin stainless steel (0.7mm or so) can be welded by argon arc. It is recommended that argon arc welding machine and 1.6 tungsten rod be used to adjust the current to 80-100.Method of using argon arc welding:1. hand weldingThe argon arc welding / manual welding "switch in the" manual welding "position, the" DC / pulse "switch is in the" DC "position, at this time can be adjusted arbitrarily according to your requirements of welding current" knob, manual electric arc welding with standard current.2. direct current argon arc weldingThe argon gas cylinder switch shall be opened before welding, and the argon flow switch on the argon flow meter shall be selected at the appropriate flow position.The argon arc welding / manual welding "switch in the" TIG "position, the" DC / pulse "switch is in the" DC "position, adjust the current adjustment knob to the appropriate value of the current, press the torch switch, Steyr argonArc welding arc for high-frequency arc, tungsten without contact with the workpiece (to prevent tungsten electrode, do not touch the arc welding) can be welded, welding end, loosen the gun switch, arc extinguishing, gas lag off gasAdjust the knob to select the delay closing time.3. pulse argon arc weldingPlace the "argon arc welding / manual welding" switch in the "argon arc welding" position and place the DC / pulse switch in the "pulse" position. Adjust the "current adjustment", "base value current" knob, so that the current adjustment is greater than the base value of the current can produce pulse welding effect. Pulsed argon arc welding can be used to accurately control the size of the weld pool, each melting point, heating and cooling rapidly, suitable for welding, thermal conductivity and thickness difference between the weldment.
04 of the thickness of 1.6 wire is too thick, the current is small, welding wire does not burn, the current is large, welding wire is turned, but the pipe can not stand.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.
.7 OK, not too thin.Pulse welder is the best.Porcelain mouth as small as possible, needle point as close as possible, tungsten as far as possible to sharpen the taper, a little bigger, that is, a bit sharp.5 litres / minute will be enough,Current 40A
