BTEB Welding Exam study guide
BTEB Welding Exam · Work through your exam, one topic at a time.
The BTEB Welding Exam refers to welding assessment under the Bangladesh Technical Education Board (BTEB), the national board responsible for technical and vocational education in Bangladesh. Candidates typically come from vocational and short-course welding programmes - SSC (Vocational), HSC (Vocational), diploma-level, and short-course institute students - who need certified evidence of practical welding skill and related trade knowledge. The board's own website lists short-course and other programmes alongside its SSC, HSC and diploma streams, and publishes syllabi, course structures and regulations for download. Assessment in welding normally combines a written or oral theory paper on welding technology - processes, electrodes, joint types, symbols, metallurgy basics, inspection and defects - with a workshop practice component covering safety, equipment set-up, bead and joint execution, and finishing. Topics on this exam: Welding Technology (BTEB vocational/short-course curriculum) and Workshop Practice and Safety. The BTEB Welding Exam study guide has 2 sections and about 833 words.
01Welding Technology: Processes, Electrodes and Defect Control
A BTEB welding candidate must be able to match a process to its power source, filler and typical use. Know SMAW (manual metal arc) : a flux-coated consumable electrode, constant-current supply, polarity chosen by electrode class. Know MIG/MAG (GMAW) : continuous wire, DC reverse polarity (electrode positive), shielding gas - argon-rich for aluminium, CO2 or argon-CO2 mixes for carbon steel. Know TIG (GTAW) : non-consumable tungsten electrode, separate filler, DCEN for steel, AC for aluminium to break the oxide film.

Workshop practice covers everything before and around the arc: joint preparation, fit-up, tacking, distortion control and inspection, plus the safety regime that makes the work legal and survivable. Know the standard joint types - butt, lap, tee, corner and edge - and the edge preparations (square, single-V, double-V, bevel, U) used as plate thickness rises. A single-V butt on 10 mm plate needs a root gap and a included angle typically 60–75 degrees so the root can be penetrated. Distortion control is examined often.
