Cleaning the metal to be welded with a degreaser will help make the weld stronger, grinding or filing the bevel along the edge of the weld will help the liquid metal penetrate deeper into the joint, clean the weld by light grinding or filing, don't Over welding will damage the weld.
The electrode tool transmits the current from the welder to the material being welded, heats it to become liquid, the electrode tip is made of non-consumable tungsten, some welds need to be fed to strengthen the joint due to the uneven or weak shape of the weld, and the welding rod Wire feed using electrode feed.
Use an angle grinder to help smooth out joints and clean metal surfaces before welding.
An electrode furnace is the basic welding material used to store the electrode, or to heat the electrode continuously.
The two copper wire cables are covered with tough insulation and are used to carry the current from the welding machine back to the welding machine. Electrode holders are required, which are lightweight and have strong thermal insulation to withstand the wear and tear of continuous operation.
The ground clip is used to connect the ground cable to the workpiece or welding table, and a cable gland is required to connect the cable to the machine.
Welding is very dangerous due to high temperatures and can be fatal if not handled properly, wear eye protection helmets, earplugs, solid boots to protect feet from sparks or slag, gloves and leather before touching welding materials and equipment Cover the rest of the body.
Welding mask can protect face and eyes from electric rays and splash of molten metal, hold with one hand and weld with the other hand, other materials are chisel hammer, wire brush, safety glasses for cutting welds, vice clamp , anvil, hammer, pliers.
An electrode is a coating-coated melting electrode used in electric arc welding. It is composed of two parts: coating and welding core.
(l) Solder core. The metal core covered by the coating in the electrode is called the welding core. The core is generally a steel wire with a certain length and diameter. During welding, the welding core has two functions: one is to conduct the welding current and generate an arc to convert electrical energy into heat energy; the other is to melt the welding core itself into a filler metal and fuse with the base metal to form a weld.
The special steel wire used for welding can be divided into three categories: carbon structural steel wire, alloy structural steel wire and stainless steel wire.
(2) Medicine skin. The coating applied to the surface of the core is called the coating. Coating a layer of coating composed of various minerals on the outside of the light electrode can stabilize the arc combustion and improve the quality of the weld. Some reducing agents should be added to the coating to reduce the oxides to ensure the quality of the weld. Due to the high temperature of the arc, some alloying elements contained in the weld metal are burned (oxidized or nitrided), which will reduce the mechanical properties of the weld. By adding ferroalloy or pure alloy elements to the coating of the electrode, it is transferred into the weld metal with the melting of the coating to compensate for the burning of the alloying elements and improve the mechanical properties of the weld metal. The improvement of welding process performance enables stable arc combustion, less spatter, good weld formation, easy slag removal and high deposition efficiency. In short, the role of the coating is to ensure that the weld metal has the required chemical composition and mechanical properties, and the electrode has good welding process performance. The main welding materials for oxygen cutting are: cutting nozzle, oxygen welding torch, oxygen cutting nozzle, flux, base metal (material to be welded), welding gloves, protective mask, etc. The main application industries are sheet metal industry, medical equipment industry, mold making, furniture factory, bicycle moped industry, boat parking industry ```It can be said that it is used in various industries. Stainless steel-aluminum alloy welding materials: aluminum-silicon solder powder 304#, aluminum-silicon solder powder 430#, aluminum-silicon flux powder.
