Case study : The hardness of Pulse Laser Welding

Which hardness (HRC) can be reached ?

This case study was recently investigated by DSI Thailand Laser-Welding-Academy . In cooperation with third party Thai-German Institute (TGI), Arun jeangsrijaroen and German Welding Society DVS – Deutscher Verband für Schwei?en und verwandte Verfahren e. V. SLV Hannover, Prof. Dr.-Ing. Gerd Kuscher .

Case study steps :

1.) Test plate welded by DSI Laser Service (Thailand) Co.,Ltd. according pWPS (preliminary Welding Procedure Specification)

Base Material : Carbon steel S45C / JIS G4051

Filler Material : DSI M 10PLUS dia. 0.6mm (selected form "DSI-Wire" program)

Test plate deposition welding : 3 layers

2.) Examined by third party Thai-German Institute (TGI), Arun jeangsrijaroen

2.1.) Macro-Cross Section

2.2.) Hardness (HRC) / Base Material / HAZ / Pulse Laser Weld

3.) Examination results double checked by German Welding Society, at DVS SLV Hannover.

4.) Quality proved : ? pWPS became WPS

Remarkable conclusion :

The Pulse Laser Weld reached a Rockwell Hardness of 66.9HRC by using DSI M10PLUS filler material.

Questions & Answers :

Q : Why PLWelding can provide such a hight hardness ?

A : Because of Welding with Pulse Light and its Speed - Within a split of a second : Check the movies : 1.) Original speed 2.) Thermo camera 3.) Super-slow speed camera

Q : Why PLWelding can provide all its Unique Advantages ?

A : Because the whole welding process is happened on "The tiny-giant Playground" which is unreachable for any other welding, cladding or spraying method.
