  Ensuring a topnotch weld inspection program​ Ensuring that welders follow specific procedures is a crucial step in the overall welding quality system. There are a number of reasons to inspect a weld, the most fundamental of which is to determine whether its quality is good enough for its intended application. To evaluate the quality of a weld, it is necessary

  Our Services Preheating

  Preheating is the act of heating the base metal before starting to weld. It is considered very essential in high thickness materials, Cr-Mo Steels & HSLA High Speed Low Alloy steels, etc… Here we are going to answer the below topics What is Preheating ? Why is Preheat Essential ? What is difference between Preheat, interpass temperature and Post weld heat treatment? How

  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 Welding Quality

  To ensure the satisfactory performance of a welded structure, the quality of the welds must be determined by adequate testing procedures. Therefore, they are proof tested under conditions that are the same or more severe than those encountered by the welded structures in the field. This page contains visual inspection tips. The following pages contain inspection methods for GMAW and physical weld

  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

  At the end of construction, and following commissioning tasks such as water flushing, water should always be present in petroleum processing equipment. Whenever this water may subsequently lead to an operational problem, or if equipment may be damaged, it is necessary to perform a drying-out operation. There are several different reasons for drying-out depending upon the type of equipment and

  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,

  Our Services What is

  Many characteristics of a weld can be evaluated during welding inspection - some relating to weld size, and others relating to the presence of weld discontinuities. The size of a weld can be extremely important, as it often relates directly to the weld's strength and performance. For instance, undersized welds may not withstand stresses applied during service. Depending on their size and/or
