Stainless steel pipe welding rod applications is extremely wide selection of pipe fittings in stainless steel welding rod, we should note the following aspects:

The same type of chromium stainless steel welding rod should be carried out more than 200 ℃ preheat and post weld tempering around 800 ℃.

Weldment heat treatment, you should use stainless steel flange pipe pieces of welding rod.

Stainless steel pipe fitting and appropriate for improving the corrosion resistance and weldability increase the amount of stability of the elements Ti, Nb, Mo, weldability chromium stainless steel flange.

Stainless Steel Electrode has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.

Stainless steel tube welding by repeated heating of carbide precipitation and reduce the corrosion resistance and mechanical properties.

Drug skin of stainless steel pipe titanium calcium and low hydrogen type. Titanium calcium type can be used for AC-DC, AC welding penetration is shallow, and easy to redness, so as far as possible with DC power supply. Diameter of 4.0 and below can be used for all position welding of 5.0 and above for flat butt and fillet weld.

Welding Electrode  use should be kept dry, lime-titania type shall be dried at 150 ℃ 1 hour, low-hydrogen type should be dried for one hour by 200-250 ° C can not be repeated drying, otherwise the drug leather easy to crack and peel off, prevent electrode drugs leather viscous oil and other dirt, so as to avoid causing the weld to increase the carbon content and impact of welding quality. Stainless steel flange welded poor, should pay attention to the welding process, heat treatment conditions and selection of suitable welding.
