100 Construction Welder Questions And Answers

21⟩ Tell me why a WPS needs qualification?

The purpose for qualification of a WPS is to determine that the weldment proposed for construction is capable of providing the required properties for its intended application.

Welding Procedure Qualification establishes the properties of the weldment not the skill of the welder or welding operator.

23⟩ Explain me are robot welds accurate?

Robot welds are extremely accurate and consistent. This welding accuracy leads to better product quality and less wasted material while typically increasing throughput and cycle speed.

Robot welds are more accurate because…

☛ They are Precise – Welding robots perform with exceptional precision of movement.

☛ They Offer Top Repeatability – Welding robots are programmed to perform the same job repeatedly, without any alteration. This eliminates welding mistakes while increasing throughput.

☛ Automation Equals Accuracy – Robotic welding is a programmed, regulated process. Unlike manual welding where the weld quality is determined by the worker’s skill, robotic welding is always the same. With proper programming, robots will help you avoid waste and boost product consistency.

25⟩ Explain me what is a robot work envelope?

A robot can only work in the area in which it can move. This area is called the work envelope. The work envelope is determined by how far the robot’s arm can reach and how flexible the robot is. The more reach and flexibility a robot has, the larger the work envelope will be.

Axes – The number of axes a robot has define its flexibility level. The typical industrial robot has six axes of movement.

Length of arm segments – The robot’s axes link arm segments which each vary in length. The length of the arms combined with the capabilities of each axis determine a robot’s reach.

Placement – Robots have different mounting options. Their work envelopes vary in scope depending on whether they are shelf, ceiling, wall, or floor mounted. Some robots can be mounted to tracks or gantry systems, which further expands their work envelopes.

Construction – A robot’s strength effects its work space. Robots have different payload capacities which in turn determine the type of EOAT that can be attached.

26⟩ Explain is there any expiry date for WPS/PQR/WPQ/WOPQ?

NO.

WPS, PQR, WPQ/WOPQ made in accordance with the requirements of the 1962 edition or any later edition of section IX may be used in any construction built to the ASME Boiler and Pressure Vessel Code or the ASME B 31 Code for pressure piping.
