There is enough sources that recommend welding parameters (available welding procedure
specifications, equipment and filler material manufacturers).
However, some precautions must be taken during the welding procedure
. It is thought that the probe of the device should be stabilized during laser exposure either by fixing the holding hand to the patient's chin or by supporting it with the opposing hand.
Keighley Labs employs a complete array of test and inspection procedures to qualify welding procedures
, welding operators and welding processes, by examining completed welds to establish their quality, integrity and compliance with specifications.

The flame welding procedure
allows the difficult control of thermal fields which can be seen in the determined results.
Infrared thermography was used to determine the transient thermal field that accompanies fusion welding procedure
in order to study the out-of-plane distortion.
The welding speeds for each welding procedure
and material were measured during the welding operations, and their welding energies were calculated as given in Table 2.
The PMCS will change the mentality of the welding industry and regulating agencies; net power will replace input power in welding codes and in welding procedure
specifications to control heat input.
The NCPWB and its members jointly develop Welding Procedure
Specifications (WPS) that conform to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessels Code, as well as to other nationally recognized codes for welding.
He adds that even in a standard operation like the gas arc welding procedure
used to join the center disc with the rim, ArvinMeritor has been able to improve efficiency through a proprietary attachment method.
"Maintenance to the piercing tip has traditionally meant a long and involved welding procedure
which, given the actual procedure time and the time needed for welds to cool properly, put the shear out of commission for a full work day," he notes.
In August 2015, the company has completed mill expansion which includes two-step welding procedure
that enhances welding speed and quality.
