First, you need to prepare the welding materials and tools, including electric heaters, soldering wires, grinders, welders, heaters, hand tools and so on.
Secondly, you need to grind and clean the electric heat pipe and the conduit of the water heater. Angle grind the joints of the electric heaters and conduits and clean them clean and greasy with a cleaner.
Next, the welding process can be divided into four stages: preheating, heating, melting and metal bonding. In the case of the preparation of the heater is to know how to master the degree of heating of the heater and the conduit, which needs to be melted at the right time. Melting should be done by gradually placing the solder wire into the heater until it is completely melted and covers the interface of the heater and conduit.
Finally, wait for the weld surface to cool and accept the quality of the weld, i.e., verify that there are no cracks or bubbles around the weld opening, and check that the weld joints are strong and withstand pressure.
In short, the welding of water heater electric heating pipe needs professional operation, tools and materials need to be fully prepared and maintained to ensure welding effect and safety. And the usual loving use and maintenance of electric heaters can extend its life and save energy.
