It shown that improvement properties joint can be obtained introducing new components parts into standard equipment. estimation te...

welding is an extremely complex process; however, due to its commercial importance, it is essential that a more thorough study of the various processes be undertaken. Three examples of areas requiring greater understanding of arc physics are presented. The first discusses heating or cooling of the metal at the cathode; the second describes variations in heat transfer using various shielding gas...

A new fiber sensor system designed for spectroscopic analysis and on-line quality assurance of arc-welding processes is presented here. Although several different approaches have been considered for the optical capture of plasma emission in arc-welding processes, they tend to be invasive and make use of optical devices such as collimators or photodiodes. The solution proposed here is based on t...

Welding is a manufacturing process, which is carried out for joining of metals by Metal Inert Gas (MIG) welding. This is the one types of Gas Metal Arc Welding (GMAW), in which Argon and Helium is used as a inert gas. Shielding gas Argon and Helium is used and consumable electrode is used which also plays role of conductor. MIG welding is versatile, gives very little loss of alloying elements a...

The results of tensile testing steel welded belts saw blades a linter machine are presented in the article. A universal was used to find stability gaskets machine. tests on study with thickness 1.5 mm and 2 using electric arc welding kemppi (a carbon dioxide technology) showed that order stretch up 5 mm, 2820 N is necessary for welding, 2900 kemppi; 3260 4440 welding. when gaskets, both can be ...

Submerged arc welding process is usually employed for welding of thick workpieces. Quality of submerged arc welded components depends on various factors. Selection of appropriate process parameters for joining metallic components is needed to obtain sound weldment. Many researchers carried out investigations to find out appropriate process conditions to obtain quality submerged arc welded compo...

The large problem to create manual welds of constant high quality results from missing optical information during the actual welding process. Due to the extreme brightness conditions e.g. in arc welding and the use of protective glasses even experienced welders can hardly recognize details of the welding pool, the welding seam and the environment. This paper describes a new research project for...

Arc welding produces the full spectrum of ultraviolet radiation (UVR). It is possible that welders are at greater risk of developing skin cancer than the general population, but there is a dearth of well designed studies in this area. The only major study of the relationship between arc welding and skin cancer risk did not reveal an increased incidence of skin cancer in welders. As the welders ...

Although solidification cracking is not usually regarded as a serious problem when welding ferritic steels, improvements in the submerged arc welding process, using higher deposition rates and faster welding speeds, have led to welding conditions more likely to give cracking. Furthermore, the need to weld stronger tougher steels, where the inspection requirements are more stringent, has led to ...
