WELDING PROCESSES

 The welding processes are not the scope of this manual, specific for welding inspections. However, only for refreshing, the most common arc welding processes used in heavy and medium carbon  and alloy steel manufacturing are:

SMAW: Shielded Metal Arc Welding – stick welding electrode;

GMAW: Gas Metal Arc Welding or MIG welding – solid wire or metal cored wire;

GTAW: Gas Tungsten Arc Welding or TIG welding – rod or solid wire.

SAW: Submerged Arc Welding – solid or tubular wire;

FCAW: Flux Cored Arc Welding – gas-shielded flux cored wire;

CAW: Carbon Arc Welding

PAW: Plasma Arc Welding

welding worktypes of welding processes

The steels commonly used in plate manufacturing, metallic structures and piping systems are covered by the specifications of ASTM, AISI, ASME, SAE, and API.

 

The specifications often refer to the same types of steels, although different restrictions on the chemical analysis and mechanical properties.

Commonly the most used materials for welded construction meet specifications conform to ASTM A 36, A 203, A 242, A 440, A 441, A 514, A 517, A 572 and A 588. For piping materials the main specifications are ASTM A 53, A 106, A 134, A 139, A 671, A 672 or A 691 or API 5L, 5LX, or 2H.

Discontinuities in Ultrasonic Testing in NDT

Image
 This blog will discuss types of discontinuities that can be evaluated with the ultrasonic testing in NDT method. Discontinuities can be divided into three general categories inherent, processing and service Inherent discontinuities are usually formed when the metal is molten. Inherent wrought discontinuities relate to the melting and solidification of the original ingot before it is formed into slabs, blooms and billets. Inherent cast discontinuities relates to the melting, casting and solidification of a cast article. Usually caused by inherent variables such as inadequate feeding, gating, excessive pouring temperature or entrapped gases. Processing discontinuities are usually related to the various manufacturing process such as machining, forming, extruding, rolling, welding, heat treating and plating. Service discontinuities are related to the various service conditions such as stress, corrosion, fatigue and erosion. During the manufacturing process, many disco

NDT on Shafts

Image
  Non Destructive Testing,NDT on Shafts is considered essential , because the shafts are mostly made as load bearing structures, any defects such as cracks will propagate more during acting of load and eventually will cause failure. The most possible defects in shafts are Cracks and Pipes , which is shown below The Non Destructive methods preferred for defect detection on raw material shafts are Ultrasonic Testing, Magnetic Particle testing / Eddy Current Testing / Magnetic Flux Leakage method. We have not discussed about other NDT methods such as Liquid Penetrant testing & Radiographic testing because for raw material inspection. These methods will be cost effective for raw material testing  ( i.e. most costly and labor intensive, also there is possibility of missing out the cracks in radiography testing due to orientation of crack ) The Defect wise identification method is given as below  , Internal Defect ( Piping ) – Ultrasonic Testing Surface Defects  (C racks) – Magnetic Part

Standards for Welding Positions

Image
  Standards for Welding Positions : It is very important for the Weld Inspector  to know the position , or location of a joint relative to the horizon, because it may determine what welding process, methods, and techniques can be used. Welding is usually easiest when the welder can work on a joint located on a flat, horizontal surface, such as on a table or bench. However, joints in the field may be located in a variety of positions relative to the welder and to the horizon, as shown below.  1)  Welding positions – AWS D1.1, European Welding Standard EN 287 – 1, ASME IX: 2) Welding Positions – Butt, Fillet and Piping Welds: Flat Butt Weld Position – 1G In this position, the axis line of the weld must  not incline more than 15°  from the horizon and the face of the weld must be on top. Welders often refer to the flat-position welding by the nonstandard term  downhand welding. Horizontal Butt Weld Position – 2G In this position, both plates are perpendicular to the bench top, but the axi
