What are the tasks to be considered during Welding Operations?

 

TASKS DURING WELDING OPERATIONS

Welding inspection during welding operations should
include all the audit parameters to verify that the welding is performed to the procedures. Such tasks may include the following:



Quality Assurance

Establish a quality assurance and quality control team
with the welding organization.

Quality control items to assess:

  • Welder is responsible for quality craftsmanship of
    weldments.
  • Welder meets qualification requirements
  • Welder understands welding procedure and requirements
    for the work.
  • Special training and mock-up weldments performed if
    required.
  • Welder understands the inspection hold-points.

Potential inspector actions:

Review welder performance with welding organization as below

weld inspection course

Welding Parameters and Techniques

Confirm welding parameters and techniques are supported
by the WPS and WPQ.

Quality control items to assess:

1.Essential variables are being met during welding.
  • Filler material, fluxes, and inert gas composition/flow
    rate.
  • Purge technique, flow rate, O2 analysis, etc.
  • Rod warmers energized or where rod warmers are not
    employed, the welder complies with maximum exposure
    times out of the electrode oven.
  • Preheating during tack welding and tack welds
    removed (if required).
  • Welding technique, weld progression, bead overlap,
    etc.
  • Equipment settings such as amps, volts, and wire
    feed.
  • Preheat and interpass temperatures.
  • Travel speed (key element in heat input).
  • Heat input (where appropriate).
2. Mock-up weldment, if required, meets requirements with welder and welding engineer.
3. Welder displays confidence and adheres to good welding practices.

Potential inspector actions:

  • Review mock-up weldment problems with welding
    engineer.
  • Review welder quality with welding organization.

Weldment Examination

Complete physical checks, visual examination, and in-process
NDE

Quality control items to assess:

  • Tack welds to be incorporated in the weld are of acceptable
    quality.
  • Weld root has adequate penetration and quality.
  • Cleaning between weld passes and of any back-gouged
    surfaces is acceptable.
  • Additional NDE performed between weld passes and on
    back-gouged surfaces shows acceptable results.
  • In-process rework and defect removal is accomplished.
  • In-process ferrite measurement, if required, is performed
    and recorded.
  • Final weld reinforcement and fillet weld size meets work
    specifications and drawings.

These are the tasks welding inspector course fees. Trainings for welders, trainings for Welding inspections, Courses and Certification for performing  NDT, consultancies for welding procedure Specification WPS , Welder qualification in Coimbatore etc., are readily available globally everywhere, for more assistance contact experts at https://aqcinspection.com/ .

    Thanks for this post…Welding codes and standards address all aspects of design and fabrication of welded components, including welding procedure specifications, quality control and quality assurance during welding and necessary welding skills for a given welding procedure in all industry sectors. The relevant code is often specified by the end user or client as a contractual agreement in order to control the characteristics of the welded components that may affect the service requirements. Compliance to these welding codes is therefore a must.

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 d...

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 rac...

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 perpendic...
