Thick-section steel is widely used in large structural applications, taking advantage of its
characteristics, including high strength, good toughness, and low cost. Ultra-high-power …

Abstract U-rib-to-deck (RTD) joints represent one of the most critical and vulnerable welding
details of orthotropic steel decks. Aiming for full penetration and high-level service …

At cold temperatures, the stress after welding a blast furnace shell is not completely released
because of the fast cooling speed, which results in cracks. To solve this problem, an …

High-power laser-arc hybrid welding (HLAHW) has emerged as a prominent method for
manufacturing medium-thick-walled steel components in modern industrial manufacturing …

The ultra-high power laser-MIG hybrid welding technique provides an effective method for
thick-walled components joining, but the fatigue properties of joints are rarely reported. This …

Welded joints of wear-resistant steel often experience wear problems due to a lack of
strengthening particles. This study investigates the wear behavior of welded joints produced …

This study investigates the effect of the propylene gas flame on the emissions and
temperature distribution of the metal plate during the preheating process. Experimental tests …

Welded joints suffer from hydrogen embrittlement (HE) owing to the internal stress
generated during welding. Alloying elements play a vital role in the metallurgical behavior of …

Thick plate steel structure is widely used in the construction machinery, pressure vessels,
ships, and other manufacturing fields. To obtain an acceptable welding quality and …
