Preparatory Questions For AWS & CSWIP Exams

Q1) Which welding process is generally preferred for large-scale, high-production applications due to its high deposition rates and ability to weld thick sections? Submerged Arc Welding (SAW) Gas Tungsten Arc Welding (GTAW/TIG) Shielded Metal Arc Welding (SMAW/Stick) Flux-Cored Arc Welding (FCAW) (Explanation: Submerged Arc Welding (SAW) is the most suitable choice for large-scale, high-production applications. […]

Q1. Which of the following welding processes would give the highest heat input when using typical parameters? Tungsten Inert Gas welding Manual Metal Arc welding Submerged Arc welding Metal Active Gas welding (Explanation: The continuous feeding of the electrode and the use of granular flux contribute to sustained and intense heat, making SAW effective for

Q1. Which welding process utilizes a non consumable electrode? SAW MMA TIG MIG (Explanation: In TIG welding, a tungsten electrode is used to create an arc, and a separate filler material may be added to the weld pool as needed. The electrode itself is not consumed during the welding process.) Q2. MMA welding (SMAW) of

Wire stick-out length Welder’s convenience Wire feed speed Inductance 3. In X-ray work the quality of the radiographic

1. Stress relieving is not helpful in which of the following cases? Softening the steel Lowering the peak residual stress Improving resistance to stress corrosion cracking Improving dimensional stability after machining 2. Stray arcing may be regarded as a serious defect because: It may reduce the thickness dimension of a component It may cause liquation

1. The Discontinuity which results from the entrapment of gas within the weld cross-section is known as: Undercut Lack of penetration Lack of fusion Porosity 2. A discontinuity can be called as a defect only when;  It is a Linear indication  It is a rounded indication  It exceeds the code limit  if it is a
