Magnesium welding wire is used as a conductive filler metal or wire welding material, it is used as a filler metal in gas and tungsten arc welding, and as a filler metal in submerged arc welding, electroslag welding and other MIG arc welding.
Magnesium welding wire is a metal product, although most of the solid core and seamless flux cored surface is copper plated, part of the surface of the flux cored is rust-proof (e.g., chemically blackened), in the packaging, in addition to the plastic bag, some of the bags are also filled with a small bag of moisture-proofing agent, and outside the cardboard box packaging, but moisture-proofing is still a problem to consider for its storage. Due to moisture absorption magnesium wire will increase the content of diffused hydrogen in the molten metal, resulting in craters, pores and other defects, welding process performance and the mechanical properties of the weld metal will deteriorate, the weld cracking is serious, which is the same as the other welding materials, of course, due to the powder in the flux cored is tightly wrapped in the steel strip, the powder has very little contact with the air, and at the same time, there is no moisture-absorbing substances such as water-glass in the electrode, so that with the cladding of the electrodes Compared with the clad welding rod, the amount of moisture absorption is very small, but if it is placed in a high temperature and high humidity environment for a long time, in addition to its surface rust, it will absorb moisture.
In order to ensure the safety of magnesium welding wire during storage, transportation and use, and to avoid personal injury or property damage, please carefully understand and observe the following safety precautions:
1. Keep the warehouse dry during storage to avoid rain or moisture rusting.
2. To use a forklift to carry the whole product, the transportation should control the speed, to prevent bumping and dumping injuries or break it, handling a single volume, pay attention to the light holding, gripping, to avoid squeezing hands and feet.
3. In use, it is forbidden to touch its surface directly with hands, and wear clean gloves before operation.
4. Wear goggles when threading or handling messy wires, and keep your face away from the position of the broken head to prevent personal injuries such as stabbing your eyes or skin.
5. The premises should be equipped with ventilation facilities to ensure good ventilation and avoid personal injury caused by fume pollution.
6. Welding spatter will burn the skin, magnesium wire arc will cause eye injury, before operation should wear labor protection equipment and welding mask.
7. The operation process should be prevented from electric shock accidents, to avoid causing personal injury.
8. The temperature of its samples or products is very high, so direct contact with the human body should be avoided.
9. After welding, there will be a small amount of welding slag on the surface of the weld, which will fly out of the workpiece after cooling, so pay attention to the protection when observing the weld.
In addition, magnesium welding wire also plays a significant role in the direction of Magnesium Profiles, Magnesium Alloy Part, and even filler Magnesium Alloy Plate.
