The GTAW process in conjunction with ER308L (W 19 9 L) or ER316L (W 19 12 3 L) wire produces the cleanest weld metal and exceptional toughness even at -196 C (-320 F). Experience has shown that with both ER308L and ER316L wires it is possible to achieve typically 80J (60ft-lb) at -196°C (-320°F) and a lateral expansion of 1.0mm (0.040inch), when using the argon shielded GTAW process.

16/8/2020· MIG welding is a welding process whereby a spool of solid welding wire electrode is fed into the welding pool, joining the two metal bases together. In order to protect the welding pool from contamination and oxidation, shielding gas is also used coming from the welding gun itself.
For arc welding carbon steel rail, I use Railend 932-0 stick, 1/4" at close to 300 amps or Railend 932-0 wire 1/16" at varying currents up to nearly 300 amps. the rail is preheated to abnout 800-1000 degrees (black-red heat in sunlight) before welding, and
Radio Frequency (RF) Welding or High Frequency (HF) Sealing Process Overview RF heat sealing (also known as dielectric sealing) uses high frequency energy to melt polar plastic material between two electrodes (RF Sealing Dies). M ost commonly used RF frequency is 27.12MHz.

GMAW-P runs cooler for the same wire feed speed, when compared to the standard GMAW spray process, and it allows the weld pool to freeze slightly to help prevent burn-through. The lower heat input the process generates offers benefits similar to those found with gas tungsten arc welding (GTAW), though GMAW-P is much faster.
The process is normally limited to the flat or horizontal-fillet welding positions (although horizontal groove position welds have been done with a special arrangement to support the flux). Deposition rates approaching 45 kg/h (100 lb/h) have been reported — this compares to ~5 kg/h (10 lb/h) (max) for shielded metal arc welding .

Welding codes and standards can be used by the welding fabrior to assist with the development of their process control system. If we examine the major elements of process control, as specified by such standards for quality systems, we will recognize those same elements as being addressed within most welding codes or standards.

The Origins of Sciaky’s Wire-based EBAM ® Process Sciaky, Inc. began developing the wirefeed EB process back in the mid-1960s. The process was further refined to build jet engine knife edge seals in the 1990s,  and, in the early 2000s, the EBAM process was developed to help manufacturers save significant time and money on the production of large, high-value metal parts.
The welding wire continually touches the base metal and arcs in an "arc on/ arc off" cycle that allows the molten weld puddle to cool enough so that welds can be made in any position, flat, horizontal, vertical, and overhead. When the wire feed gun trigger is pulled
