lascondities

Lascondities is a Dutch term used in engineering to denote the environmental and process-related conditions required for welding operations. It covers material type, surface preparation, joint design, welding method, and a range of controllable process parameters and environmental factors that affect weld quality. Typical elements include base metal and coatings, preheat and interpass temperatures, shielding gas, current and voltage, travel speed, fit-up, cleanliness, humidity, and post-weld cooling, along with inspection criteria. The term appears in Dutch standards, specifications, and quality documentation.

Etymology and usage: Lascondities combines las (welding) and condities (conditions). It is normally written as a single word in Dutch and is translated as “welding conditions” in English. In English, the more common terms are “welding conditions” or “welding parameters.” The distinction is context-dependent: conditions refer to environmental and material factors, while parameters refer to adjustable process settings.

Context and application: In practice, lascondities are specified in welding procedure specifications (WPS), codes, and qualification records to ensure repeatability and compliance with standards such as ISO or EN. Properly defined lascondities help prevent defects by maintaining consistent heat input, shielding, cleanliness, and post-weld treatment.
