It is a short circuit transfer process controlled by adapting the waveform (see figure) and arc welding filler metal. Reduce projections by diluting the strength of current, whenever a short circuit occurs in the arc. The touch of gout and bathroom breaks by surface tension and the metal is deposited gently without splashing.

Defined as a type of metal transfer that combines the high frequency wave control, for stability and power of arc wide gap joints made without using ceramic support or backing plate (backing).The result of these solders enables high performance, with ensembles consistent, clean and of excellent quality. The current machines can wean the current value of the feed rate.

Control Technology Using Waveform TM, used machines has the ability to share and change the current electrode in microseconds. The precise control of the electrode current during the complete cycle of welding minimizes or even eliminates the main drawbacks of the conventional mode of GMAW short arc welding.

The STT process shows its full potential when welding thin materials and cord root, for example, tubing. The process is effective welding stainless steel and related alloys and mild steels and high strength. In steel, it offers the ability to use 100% CO2 welding producing low hydrogen content.

Stainless steel and other related can be used several shielding gases including argon and helium mixtures. When duplex stainless steel weld metal properties can be even higher. The Lincoln Electric Company is the first and only company that maintains the Patenet welding and began this revolutionary new welding process called Surface Tension welding process called Surface Tension Transfer ® (STT ®). Transfer ® (STT ®).

Originally pat-Originally patented in 1988, it was not until 1994 thatentado in 1988, but it was not until 1994 that the first commercial unit was produced the first commercial unit was sold producidaand. and sold. Today this process is welding Today this welding process is being used by every major pipe being used by each of the main contractor plumbing contractors in the world, yet it is still in the world, but it is still relatively unknown in many manufac-relatively unknown in many sectors of manufacturing structures.
