Use Basic Hand Tools
Shielded Metal Arc Work (SMAW) is also known as stick welding or manual metal arc
welding. Welding is a process of joining two similar metal pieces by heating to a fluid state
(melting), with or without filler material or pressure. For someone to do the task, he/she must
have tools. In this lesson you are going to familiarize yourself with the basic hand tools used in
welding.
Learning Outcome 1- Identify and select materials and tools
To get started with your welding, you must have a set of at least basic equipment and
tools and here’s a list of the basic welding hand tools and their uses.
Welding hand tools are grouped into four categories

Requisition of Materials and Tools
Requisition is made through a required form known as requisition slip or in the form of a
letter, if the previous is not available. Most government offices use uniform requisition slip, while
others have their own. In school shops, teachers are creative enough to devise their own form to
suit their local need. Such practice of using requisition slip promotes proper monitoring of
supplies, materials, tools, and performance and accomplishment of required service or services
among others. Here are some examples of requisition forms according to their purpose.
A. Requisition Slip
Name of School: _____________________________________

The following are the terminologies found in a requisition form:
1. Name of Project indicates the task in which the materials will be used.
b. Example: Repair of School Lavatory
2. Balance On Hand indicates the quantity and unit of materials still available in the
stockroom
3. Requisition Quantity and Unit is a number and units of materials requested
4. Unit write the unit of measuring quantity
5. Material/Description write the name of material and description or specification
6. Unit Price is a price of material per piece or per unit
7. Total is a unit price X Quantity (ex. 3 pc x P30 = P90.00)
8. Borrower is a name and signature of the person requesting tools and materials.
9. Tool Keeper is the one who is responsible to take care the of the tool room.
10. Job Order is workings sheet that server as a complete guide of the student to a certain
task to be done.
11. Foreman is a person responsible in the overall operation of the worker in the
workplace.
Borrower’s Slip
This form is used for borrowing materials, tools, equipment. Its use promotes proper monitoring
of inventories. It has numerous purposes and outweighs disadvantages. This form is devised
according to the need of the office or accountable officer. Adopting this system necessitates
observing certain rules and penalties for violators.

REQUISITION PROCEDURE
In making a request for materials and tools needed, the following Standard Operating Procedure
(SOP) should be followed:
1. List down the materials and tools needed as per job requirement.
2. Check for the availability of the needed materials and tools in the stockroom.
3. Accomplish a requisition form
4. Let the shop teacher check the requisition form.
5. Submit the requisition form to the material officer
6. Unavailable requested materials and tools should be substituted without sacrificing the cost
and quality of work
7. The material officer will prepare the requested material for issuance to the student.
Acquire and Inspect Materials/Tools
It is important to inspect and check materials and tools for defects and damage before receiving
them so that you can ask for replacements for those that you found defective.
1. Check if the materials and tools are complete in terms of quantity and specification (number
of pieces, length, width, etc.)
2. Check the physical condition of tools, (check tools against the specification, quantity, and
quality,) see to it that parts are complete, cutting edges or tooth free from damages,
3. Check the accessories of each material and tool. See to it that nothing is missing.
4. If any of the materials or tools is found missing or defective, report it immediately to the
supply officer or teacher.
5. Get a replacement for the materials and tools found defective.
6. Sign the requisition form as you receive materials and tools.
7. Store the received materials and tools in a safe area or storeroom nearest your workplace.
(store materials, in proper order, bulky and heavier materials at the bottom lighter and
smaller items on top of the pile)
8. Always handle the materials and tools carefully. (avoid dropping the tools on the floor, do not
expose tools and materials on sunlight or rains)
