Ensuring the correct travel speed and technique is fundamental to improving weld quality because it directly influences the heat input, penetration, and overall appearance of the weld. If the travel speed is too fast, it can result in inadequate penetration and insufficient fusion between the base materials and the filler material, leading to weak joints. Conversely, if the travel speed is too slow, it may lead to excessive heat input, causing defects like burn-through or warping.

Correct technique also encompasses maintaining the proper angle of the welding torch or electrode, controlling the distance between the welding tool and the work surface, and applying consistent movement patterns. All these factors together contribute to the formation of a sound weld with good mechanical properties and minimal defects, such as porosity or slag inclusion.

Other options offered would not contribute positively to weld quality. For instance, using low-quality materials can compromise structural integrity and performance. Shortening the weld time could increase the likelihood of defects due to improper fusion and inadequate heat treatment of the weld joint. Welding without preheating can lead to issues like cracking in certain materials, particularly in thicker sections or those prone to thermal stresses. Each of these practices can adversely affect the final outcome of the welding process.
