Preheating involves heating the base metal, either in its entirety or just the region surrounding the joint, to a specific desired temperature, called the preheat temperature, prior to welding. Heating may be continued during the welding process, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external heat source. The interpass temperature,

The descriptive term provides an important clue, so we're ready to take a guess at the role this test technique plays. Being engineers, however, there's no room for guessing, so let's get the explanations down in black-and-white right now. Hydrostatic testing, as utilized on a pressure vessel, uses water as a seal inspection medium. It is Technically a Non-Destructive Test Technique Pressurized
Have you heard of post weld heat treatment (PWHT)? Of course you have. If you are involved in welding you have definitely heard this term. But what is PHWT? When is PWHT required? What temperature should PWHT be done at? Heat treating of materials can be a very complicated subject, but when it comes to heat treatment after welding it boils down to a simple concept: PWHT is done in

Induction Heating The most common methods for achieving a more controlled preheat temperature are induction heating and electrical resistance heating. “The equipment used for induction is considerably more expensive than that used for electrical resistance heating,” said Fong. “However it does get your steel hotter quicker. It still offers you much more control than what you

Welding Welding is basically the mixing of abase metalwithfiller metal. Filler material is melted at high temperature through a consumableelectrodeand provides the relevant bonding strength. Filler metal and base metal are bonded together in one solid body. A good quality weld is at least as strong as the base material(s) being joined. Preheating Preheating is

The procedure of Post Weld Heat Treatment projects is often recorded in a quality document beforehand. It lists the requirements that should be met for the relevant heat treatments and that will lead to a guaranteed result. Post Weld Heat Treatment (PWHT) is the international term for stress relief annealing: a heat treatment that is carried out – among other things – after welding work

Preheating Heat treatment of welds is a critical activity which needs to be carried out before and after the welding process. Heat treatment before welding (Preheating) is necessary to bring the base weld metal at proper temperature. No welding shall be performed without preheating the joint to 10°C (50°F) when the ambient temperature is below 10° C. Preheating requirements for

We all have probably heard about destructive testing in welding. After all, those of us who are certified welders or work at a place that needs to certify welding procedures, have at one time or another heard about a bend test, or a charpy v-notch test. However, there are several types of non-destructive testing available. As you can imagine, performing destructive testing on

PostHeating In case of alloy steel materials such as Cr-Mo stels, if the post weld heat treatment is not performed immediately after welding, then the weld joint and adjacent portion of pipe, at least 50 mm on either side of pipe, shall be uniformly heated to 300°C. This temperature shall be maintained for half an hour minimum, and then wrapped with mineral wool before allowing it to cool

APRIL 7, 2017Featured Stories Transmission pipeline welding often requires preheating of the weld zone to ensure that the joint achieves its required strength and hardness. Proper preheating also helps minimize the risk of delayed hydrogen-induced cracking, which is a significant concern that impacts weld quality and integrity in transmission pipelines. There are several heating methods

As anyone in the fabricating and welding business knows, process and part inspection is a critical component of a successful business. Build and weld a poor part will simply guarantee failure. Today, welding associations, such as the Canadian Welding Bureau, offer certification courses to help welders learn the ins and outs of proper inspection processes, but before taking the course, you should

Welding processes can introduce contaminants and metallurgical defects into a component. Applied Technical Services offers NDT welding inspection on structures, both ferrous and non-ferrous, or components to detect surface and sub-surface defects and discontinuities. In order to meet quality and safety standards, welds are commonly required to withstand load and stress conditions.
