Electric shock is a common major danger for all welding methods that use electric energy to convert heat energy. In the welding operation, the welder has many opportunities for contact with electricity, often requires live work, such as contact weldments, worktables, welding clamps, or welding torches, as well as frequent live work such as adjusting welding current and replacing welding rods. Hands are on the side, and sometimes they need to stand on the weldment and operate at the feet. If there is something wrong with the electrical device, there is a defect in the protective mask or the safety operation rules are violated, electric shock may be caused. Especially in the operation of the container pipeline, all around the metal electrical conductors, the greater the risk of electric shock.
In addition, electrical fires, explosions, and scalding accidents may occur, mainly due to electrical fires caused by overloading, short-circuiting, and excessive contact resistance of welders and lines; near the operating point or under overhead working sites, flammable and easy to store. Explosives, fires and explosions caused by sparks and Mars splashes, explosions of gas cylinders during gas shielded welding and plasma arc welding, and repair welding repairs of fuel containers (eg oil tanks, gas tanks, etc.) and pipelines. Welding, when the protective measures are not appropriate, are prone to serious accidents such as fire and explosion. The above fire and explosion accidents and spark splashes during operation may cause hot flashes.
There are many welding operations at height, and in addition to the danger of falling directly from high altitudes, there may be a second accident that is caused by an uncontrolled electric shock and falling from the sky. Most of the bulky weldments are welded, and mechanical injuries such as crushing, crushing, and bruising may occur.

A Hammer Drill, also known as a percussion drill or impact drill, is a power Tool used chiefly for drilling in hard materials.It is a type of rotary drill with an impact mechanism that generates a hammering motion. The percussive mechanism provides a rapid succession of short hammer thrusts to pulverize the material to be bored, so as to provide quicker drilling with less effort. If a hammer drill's impact mechanism can be turned off, the tool can be used like a conventional drill to also perform tasks such as screw driving.
