STRECKER offers a comprehensive range of special machines.
The resistance roller seam welding delivered by the HRS4000 is a form of welding which is one of the resistance pressure welding processes and was derived from resistance spot welding.
In sheet metal production, coils are joined endlessly in rolling and coating lines. The overlap seam is the most frequently used for reasons of expense. A disadvantage is that a thickening of the cross-section remains in the seam area of both sheets. The latter results in notch effects and crevice corrosion, which is negligible for a pure process seam.
The tungsten inert gas welding of the WSW series is a welding process belonging to the group of gas-shielded welding which is an arc welding process. In TIG welding, an electric arc burns between the workpieces and an electrode made of tungsten.
To prevent the melt from reacting with the ambient air, inert shielding gases are used because they do not react chemically with the materials involved. These are often argon or argon-nitrogen mixtures.
The BSM-E for single-wire applications is specially designed for flexible use thanks to its battery operation. A lightweight design, simple operation and high battery capacity are key factors in the use of this machine.
Every day, thousands of STRECKER welding machines are used worldwide to produce precise and repeatable butt welds.
