  Our Services Austenitic

  Austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength, when compare to a typical carbon steel. A carbon steel on cooling transforms from Austenite to a mixture of ferrite and cementite. With austenitic stainless steel, the high chrome and nickel content suppress this transformation keeping the material fully austenite on cooling (The Nickel

  Our Services Preheating

  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

  Our Services Inspection

  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

  Our Services Post Weld

  Chromium carbides form in stainless steels along either side of a weld. These carbides form where the metal is in the temperature range of approximately 1100 – 1500 F. Since the weld pool is well above this temperature and the base metal is below it, there is always some part of the welded part which was in that temperature range. The quantity of carbides which form depends on several factors,

  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

  Our Services NDT Welding

  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.

  Our Services Overview

  Weldingis an essential part of operating and maintaining assets in the petroleum (upstream, midstream, downstream) and chemical processing industries. While it has many useful applications, the welding process can inadvertently weaken equipment by imparting residual stresses into a material, leading to reduced material properties. In order to ensure the material strength of a part is retained
  

• 
  Our Serices Preheating

  A crucial step in many welding applications, preheating slows the rate of cooling in a finished weld, lowers the amount of hydrogen in it, and reduces the risk of cracking. Artificially introducing heat into the base metal — by means of an external heat source — adds a step to the welding process; however, it can save you time and money in the long term by reducing the potential for a failed
