ITI WELDER- आईटीआई वेल्डर कोर्स
ITI Welder Course Details Fees, Duration, Syllabus 2023
So, I would really like to inform you which you are on the proper location due to the fact in this text I even have supplied all of the records associated with the ITI welder path. ITI Welder is one of the fine short-time period publications in ITI of a 1-12 months duration.
The minimal instructional qualification for doing this path is 8th pass. It is a process-orientated path as some distance as process possibilities are concerned. Welder change can be to be had in maximum ITI colleges. However, the path expenses for ITI welder range from university to university. ITI Welder is a fundamental stage path in that you get greater realistic expertise than theoretical expertise. This type, of path, is supplied due to the fact the scholars may be talented in a single issue and take a process on that basis. The welder change is classed below the Craftsman Training Scheme run through the Directorate General of Training.

Welder in ITI COURSE INFORMATION
In engineering industry, joining of different type of metals is necessary to make various components/parts having different shapes. Various type of parts are joined by bolting or riveting if thickness of metal is more. Example: lron bridges, steam boilers, roof trusses, etc. For joining thin sheets (2mm thick and below) sheet metal joints are used. Example: Tin containers, oil drums, buckets, funnels,
hoppers etc, also thin sheets can be joined by soldering and brazing. But very heavy thick plates used in heavy industries are not joined by riveting or bolting as the joints will not be able to withstand heavy loads. Also, the cost of production will be more. So many special materials for special applications like space ships, atomic power generation, thin-walled containers for storing chemicals. etc have been developed in the recent years. They can be joined easily at a lower cost with good joint strength by using welding. A welded joint is the strongest joint of all the other types of joints, The efficiency of a welded joint is 100% whereas the efficiency of other types of joints are less than 70% So all industries are using welding for the CG & M of various
During the one-year duration a candidate is trained on subjects Professional Skill, Professional Knowledge and Employability Skills related to job role. In addition to this a candidate is entrusted to undertake project work and extracurricular activities to build up confidence. The broad components covered under Professional Skill subject are as below:
The practical skills are imparted in simple to complex manner & simultaneously theory subject is taught in the same fashion to apply cognitive knowledge while executing task. The safety aspects cover components like OSH&E, PPE, Fire extinguisher, First Aid and in addition 5S being taught. The practical part starts with edge preparation by hacksawing, filing and fitting followed by Oxy Acetylene Welding & Brazing, Oxy Acetylene Cutting, Shielded Metal Arc Welding, Gas Metal Arc Welding, Gas Tungsten Arc Welding and Spot Welding, Plasma Cutting and Arc Gouging. These processes are widely used in Industries.
During the practice on Welding / Brazing process, the trainees will learn to read the job drawing, select the required base metal and filler metals, cut the metals by appropriate process, carry out edge preparation, setup the plant and do welding/Brazing on M.S, SS, Aluminium and Copper in different positions. On completion of each job the trainees will also evaluate their jobs by visual inspection, and identify the defects for further correction/improvement. They learn to adapt precautionary measures such as preheating; maintaining inter-pass temperature and post weld heat treatment for Welding Alloy steel, Cast Iron etc. The Work Shop calculation taught will help them to plan and cut the required jobs economically without wasting the material and also used in estimating the Electrodes, filler metals etc. The Workshop Science taught will help them to understand the materials and properties, effect of alloying elements etc. Engineering Drawing taught will be applied while reading the job drawings and will be useful in understanding the location, type and size of weld to be carried out.
The professional knowledge taught will be useful in understanding the principles of Welding, Brazing, induction and Cutting process, use of jigs and Fixtures, distortion and methods of control, selection of consumables and to take precautionary measures for storage and handling and apply the same for executing the Cutting, induction Welding, welding and Brazing.
The knowledge and practice imparted on Destructive and Non-destructive testing will be use in understanding the standard quality of welds and to carry out shop floor Inspection and test in laboratories.
GENERAL
The Directorate General of Training (DGT) under Ministry of Skill Development & Entrepreneurship offers a range of vocational training courses catering to the need of different sectors of economy/ Labor market. The vocational training programmer are delivered under the aegis of Directorate General of Training (DGT). Craftsman Training Scheme (CTS) with variantsand Apprenticeship Training Scheme (ATS) are two pioneer schemes of DGT for strengthening vocational training.
Welder trade under CTS is one of the most popular courses delivered nationwide through a network of ITIs. The course is of one-year duration. It mainly consists of Domain area and Core area. In the Domain area (Trade Theory & Practical) imparts professional skills and knowledge, while the core area (Employability Skill) imparts requisite core skills, knowledge, and life skills. After passing out the training program, the trainee is awarded National Trade Certificate (NTC) by DGT which is recognized worldwide.
Trainee broadly needs to demonstrate that they are able to:
• Check the job/ assembly as per drawing for functioning identify and rectify errors in job/ assembly.
PROGRESSION PATHWAYS
• Can join industry as Technician and will progress further as Senior Technician, Supervisor and can rise up to the level of Manager.
• Can become Entrepreneur in the related field.
• Can join Apprenticeship programmed in different types of industries leading to National Apprenticeship certificate (NAC).
• Can join Crafts Instructor Training Scheme (CITS) in the trade for becoming instructor in ITIs.
