Welder

ITI Welder Trade Syllabus

The ITI Welder trade is a one-year vocational training program under the Craftsman Training Scheme (CTS), regulated by the National Council for Vocational Training (NCVT). This course trains individuals in welding techniques, safety practices, and metal fabrication to prepare them for careers as welders in industries such as manufacturing, construction, and automotive. The syllabus is divided into two semesters, each lasting six months, and includes theoretical knowledge, practical skills, and employability training.

Course Overview

• Duration: 1 Year (2 Semesters)
• Eligibility: Minimum 8th-grade pass (some institutes require 10th-grade pass with Science and Mathematics)
• Objective: To develop skilled welders proficient in gas and electric welding, capable of performing industrial welding tasks with precision and safety.
