You don't want to be holding on to your work while you weld
, so use magnets, welding tables, and tack welds
to keep your work in position.
The minitab software has been used to investigate the interaction of each welding parameters on weld strength.
Two-dimensional plane strain finite element analyses were carried out in order to obtain the computational stress intensity factor solutions for the pre-existing cracks between the upper and lower sheets near the roots of the continuous welds
with idealized and realistic weld
Figure 5 shows the normalized tensile strength of the welds
prepared under different welding parameters.
In the visual inspection, throat thickness of fillet welds
The FSW process has been used to make welds
in aluminum up to 3-inch (76.
There is a difference between the molten pool formation location due to the arc alone in TIG-YAG hybrid welding and YAG-TIG hybrid welding but, in both cases, when the YAG laser was irradiated onto the moltenpool, easily formed by the action of the arc alone, a deep penetration could be formed, except that all the welds
were not fully penetrated welds
Burn back is the formation of a weld
in the contact tip that occurs when the wire feed speed is too slow or if the gun is held too close to the work piece.
The hybrid laser-arc process could be realized using two different layouts for heat sources, or rather laser source could be the first that welds
the metal (Laser leading hybrid process) or the last one (Arc leading hybrid process).
Oil and gas companies have stringent inspection requirements for checking welds
, but Optical Metrology Services claims there are few tools on the market that can perform that work.
A key component of the system is a patented closed-loop control that allows the system to monitor the weld
joint in real time and modify the process to accommodate a joint mismatch.
If you encounter weld
problems or horn failures, FEA can be used to analyze horn integrity and assembly performance.
