1, generally suitable for the following sheet of 6mm welding, welding with beautiful appearance, the characteristics of small welding deformation.Standard Stainless Steel Plate Sizes

2, the protective gas is argon, the purity is 99.99%. When the welding current of 50 ~ 150A, argon flow rate of 8 ~ 10L / min, when the current is 150 ~ 250A, the argon flow rate of 12 ~ 15L / min.

3, the length of the tungsten electrode protruding from the gas nozzle to 4 ~ 5mm is better in the fillet welding and other obscured poor place is 2 ~ 3mm, in the slot deep place is 5 ~ 6mm, the nozzle to the working distance is generally not more than 15mm.304 stainless steel pipes

4, in order to prevent the emergence of welding stomata, welding parts such as rust, oil, etc. must be clean.Hot Rolled Flat 304 Stainless Steel Bar

5, the welding arc length, welding ordinary steel, the 2 ~ 4mm is better, and welding stainless steel to 1 ~ 3mm is better, too long to protect the effect is not good.Hot Rolled Steel Angle Prices

6, butt backing, in order to prevent the back of the bottom of the bead is oxidized, the back also need to implement gas protection.

7, in order to argon gas well to protect the welding pool, and to facilitate the welding operation, the tungsten center line and welding parts should generally maintain 80 ~ 85 ° angle, filler wire and the workpiece surface angle should be as small as possible, Generally about 10 °.

8, wind and ventilation. Where there is wind, please take measures to block the network, and in the room should take appropriate ventilation measures.
