Many types of welding wire, welding wire 2 mm and 3 mm , welding wire of iron, wire welding for Tin, copper welding wire, welding wire 3 phase. Welding electrodes and conductive cores to provide electric welded surface. The electrodes consist of throwing test pressure in private rooms.
start working with inverter welding machine, How to cook inverter welding? Today we can say quite confidently that welders on the market everyday tools systematically replacing their traditional counterparts transformer. inverter welding easier, smaller, better quality weld, less demanding welding experience in the Executive, and in some cases compensate for the lack of such experience.
How to choose a welding inverter Any house master periodically required to attach the hinges to the gate, the old car body repair , weld metal pipe , etc. , for which he needs to use electric welding . Many people in such cases, hire professionals . However , there are those who prefer to […]
How to learn welding –In the daily life of welding works are very much in demand. From time to time and have to resort to them at home, in the garage, and on a summer residence. It goes without saying that each time to seek assistance from strangers is not an option. So it’s worth […]
What can distinguish features stainless steel welding? This material belongs to the well-being welded, but has its own specifics. Stainless steel comprises iron and the additional element in an amount of 10-30% (often chromium also using nickel, titanium, molybdenum). Among its physical properties include low thermal conductivity (approximately 1/3 of the standard carbon-rolled steel) and high linear expansion coefficient. Specificity of welding associated just with the presence in the composition of the alloying element, stainless steel imparts its properties. High temperatures lead to the formation of chromium carbide compounds, which negatively affects the properties of the steel, and leading to its brittleness. To prevent this, welding technology is constantly improving. Selection of the optimal welding process largely depends on the thickness of the sheet, the alloying element and the nature of the use of the finished product (outdoor or indoor, with temperature difference or not, whether large physical impact). Today, the most popular and widely used method is the argon-arc welding (TIG). It combines the features of an electric (arc) and gas (use of inert argon gas) welding. Among the great things about TIG – excellent quality of welds, the possibility of modulating the current parameters, welding in different planes.
To implement the self-welding workers are allowed at least 18 years that have passed a medical examination, an introductory briefing, primary instruction, education and training in the workplace, testing knowledge of labor protection requirements, having a group of electrical wind chill II, professional skills and having a gas-welding works Certificate for production of gas welding works.
