1. Before welding, clean up the maintenance area, and brush chlorate flux on the welding surface;2. Before welding, the heat exchanger shall be placed horizontally, and the heat exchanger shall be filled with water, and the welding area shall be wrapped with wet cloth to avoid the high temperature generated during welding being transmitted to the nearby area to melt other places or affect the welding strength;
3. The silver base electrode used for welding shall have a silver content of at least 45%, and the temperature shall not exceed 650 ℃ during welding, so as not to affect the welding strength;
4. The continuous welding time should not be too long to reduce the influence of excessive heat.
