Orbital welding is used in pipeline construction and prefabrication, semiautomatic GTA-, GMA- and GMA-tandem welding processes are most commonly used but also manual metal arc welding is still in use. Traditional welding processes have limitations concerning welding speed and penetration. Modern laser t...$28.00

Shortage of resources demands a consequent lightweight design with aluminum. Process stability and a high seam quality in welding processes of this material are difficult to achieve especially for hard to weld materials like EN AW-6060. Bifocal hybrid laser welding (BHLW) demonstrates how this material can be welded reliable wi...$28.00

In laser welding, the low heat input in some cases results in a weld which has a high hardness compared to the base material. This can create problems in some cases, where higher fatigue life for the weld is required. One method to improve this problem ...$28.00

Laser GMA hybrid welding where both processes are acting simultaneously in one process zone and where the filler material is molten by the relatively inexpensive electric energy in the arc and not by the beam is the best remedial measure. The increased energy-per-unit length in laser GMA hybrid welding has, however, compared with laser beam welding with cold wire, sometimes a negative infl...$28.00
