An investigation concerning laser beam — GMA — hybrid welding of high strength steels has been completed for a crane plant.

The applicability of methods for determination of preheat temperature was checked by experimental welding for both two and three dimensional heat conduction. Slag metal reactions during submerged arc welding of alloy steels, Metall. A new lower cost MPa TMCP steel with high strength,good low temperature impact toughness,low yield ratio and excellent weldability has been developed successfully by design of alloy composition and thermal mechanical control process technology, and the welding heat affected zone HAZ have been investigated.

Sources of weld metal oxygen contamination during submerged arc welding, Welding Journal, vol. The type, size and distribution of the non-metal wflding in steels has been studied by optical microscope and scanning electronic microscope SEM.

Slag metal reactions in binary CaF2—metal oxide welding fluxes, Welding Journal, vol. Our aim is to develop a welding procedure giving good quality of spot weld, thus the problem of hardened and brittle spot welds would cease to exist. The mechanical properties of temper-grade steels can be modified in a wide range by heat treatment.

There are many methods available to determine preheat temperature. Welding difficulties were associated with hard and brittle spot weld nuggets and fusion weld heat affected zones being caused by nitrid.

Issues in Welding of HSLA Steels

The principle of heat treatment lies in the good hardenability, so when such steels are welded it is very likely that the heat affected zone is hardened. The microstructure and mechanical properties of base metal and samples undergoing welding thermo-simulation were also analyzed.

The researchers, developers and technologists use every effort to try to produce steels with compound properties.

In the Automotive Industry draft mostly the claim of loose of weight and increase the safety reserve. The comprehensive performance of steel can meet fully the high-technical requirements of large-scale engineering. With the increase of demand; other issues like the selection of filler grade and selection of suitable welding process for the joining of these steels have become very significant.
