Arc welding, as any industrial occupation, presents many hazards. However, welding is a safe procedure, provided that correct risk assessment is completed, observed and protective equipment used. Always use approved welding safety equipment.

A weld can be defined as a coalescence of metals produced by heating to a suitable temperature with or without the application of pressure, and with or without the use of a filler material.In fusion welding a heat source generates sufficient heat to create and maintain a molten pool of metal of the

Why beginners should start with MIG weldingSetting up is quick and easy: Beginners are ready to start MIG welding within minutes with these few steps:Connect the torch and cableConnect work cable/clampInstall a wire drive roller matching the wire sizeLoad the wire spoolConnect the power cord to an o

The damage caused by light is mainly due to the temperature effect and photochemical reaction caused by its absorption of energy, which causes biological damage. The primary mode of damage depends on the wavelength of light and the tissue exposed. For the hazards of lasers, the main cause of damage

Porosity is common in aluminum welding. In the base metal, there are a certain amount of pores in the welding wire, so it is necessary to avoid large pores during weldingto ensure that the pores do not exceed the standard. When the humidity exceeds 80%, be sure to stop welding, the probability ofblo

The sticking electrode is the adhesion phenomenon between the electrode and the part caused by abnormal welding of the electrode and the part when the welder is spot welding.There are four main reasons for sticking electrodes in the welding process: the working surfaces of the two electrodes are not

Welding is a process in which the material of the workpiece to be welded (same or different) is heated or pressurized or both are used,and whether or not to use a filler material, so that the material of the workpiece can achieve atomic bonding and form a permanentconnection process. So what are the

Causes of porosity1. Base metal is dirty, the groove edge is not cleaned2. The composition and properties of the welding materials used are quite different from those of the base metal3. Welding shielding gas problema) Insufficient argon pressure in the cylinder;b) Excessive adjustment of welding ga

Tempering is one of the most likely types of accidents when using an acetylene gas cutting torch for gas cutting operations. It is a phenomenon in which the acetylene gas flame enters the torch nozzle and burns backwards. It is characterized by the sudden extinguishment of the flame and a rapid "his
