1. The electrodes should be kept dry when using titanium calcium type by drying at 150 deg.c for 1 hours, low hydrogen by drying at 200-250 Deg. C for 1 hours (not repeated drying, or medicine skin easy cracking), prevent the covering of viscous oil and other dirt, lest cause the weld increase the carbon content and the influence of welding quality. When the elbow is welded, the carbide is repeatedly heated to reduce the corrosion resistance and mechanical properties. After the hardening of the larger, easy to produce cracks. If the same type of electrode welding, must be more than 300 degrees above the preheating and welding of 700 degrees after the slow cooling treatment. If the welding parts can not be heat treatment after welding, should use the chromium nickel stainless steel welding rod.

2. And appropriate to increase the amount of elements Ti, Nb, Mo stability etc. in order to improve the corrosion resistance of stainless steel elbow and welding, welding is better, the same type of chromium stainless steel electrode, tempering should be 800 degrees Celsius above 200 DEG C for preheating and post weld. If the welding parts can not be heat treatment, the use of chromium nickel stainless steel welding rod.
