Hello everyone,
I have a question about GMAW short-circuit. This process was selected for some out-of-position joints, and it is not possible to use another process or change the transfer mode. We have encountered lack of fusion in these field welds.
I believe that increasing the joint angle...
Hi,
Could someone please call me and explain the objective of using fillet welds to reinforce PJP or CJP welds?
I read that they help prevent stress concentration and increase fatigue strength, but why?
I think that this is because stress is better distributed.
Also, could you recommend a...
Hi Everybody,
I have a question regarding the use of undermatching filler metal in the qualification of welding procedures under AWS D1.1.
I understand that it is permissible to use undermatching filler metal if the engineer agrees to it or if it is acceptable for the application.
However...
Hi everybody, I have a question. Thank you for your time.
We need to remove a complete weld on a shell that belongs to a pressure vessel. The removal will be performed by grinding.
We will remove both the weld metal and the heat-affected zone (HAZ).
Here’s the question: the HAZ on austenitic...
Hi everybody,
I would like to hear your opinion on the influence of thickness in welding and why it's so important.
I know that it can affect the cooling rate, for example in carbon steels and low alloy steels. When the thickness is increased, it's more probable that welding generates harder...
Hello everybody, I have some questions regarding Nitronic 50 welding. I conducted some tests using the GMAW and SMAW process with ER209 as the recommended filler metal for welding Nitronic 50 to achieve similar mechanical properties. However, the impact properties of the weld metal are low...
