Welding Defects Tolerance VS Main Construction Codes

Online /
Dec 8, 2020 /
Course Code: 11-1207-ONL20

  • Overview
  • Syllabus
  • Instructor


Please Note:
This course is held online over 1 day on the following schedule (All times in Eastern Time Zone):
10:30 am to 6:00 pm Eastern (Will include the usual breaks and a 30 mins lunch)

After participating in this course, you will be able to:

  • Identify causes of weld defects
  • Understand the welding defects tolerances of each standard
  • Understand why the tolerances vary for the same welding defect depending on the type of equipment, its position, orientation, etc.

Welding defects are the result of poor control of the essential and non-essential welding main variables described in the welding procedure specification. However, are all welding defects unacceptable by the chosen standards of construction? Yes, under certain limits.

This course will explain why some welding defects can be accepted, and at the same time reduce the costs of non-quality weld seams. This course will focus on the differences between each of the different construction standard philosophies and clarify why the same defect is at times accepted and/or rejected.

Course Outline:

  • Welding defects discussion based on the a few standards
  • Visual inspection requirements
  • Porosities, undercuts, cracks, reinforcement, overlap, arc strike, spatters and high and low

Who should attend:
Engineers • Professionals in the Field • Inspectors • Welders • Technicians • Contractors
