• Working in specific circumstances, in particular:
◦ in confined spaces;
◦ above water;
◦ near below surface infrastructures;
◦ installations in operation;

• Estimation of mass and quantities of scaffold material by means of rules of thumb;
• Assessment of the strength, stiffness and stability of a scaffolding by means of rules of thumb;
• Drawing up a material state on the basis of drawings / sketches of complex scaffolding;
• Assembly, adjustment and disassembly of scaffolding on the basis of data provided by the client;
• Implementing the Scafftag procedure for small scaffolding (on the basis of competences declared competent by the employer);
• Coordination
of work on ordinary scaffolding for upcoming scaffolding builders and scaffolding construction technicians, with special attention to: ◦ safety and efficiency;
◦ Reporting on and communication with foreman and client.

   Recognize safety hazards in the scaffolds listed by the training organizer.

Scaffold Erecting and Dismantling 

The purpose of this procedure is to ensure scaffolding is adequate for the work to be performed and properly erected and dismantled. It covers selecting, erecting, and dismantling all types of scaffolds. It applies to workers, supervisors, scaffold qualified persons, scaffold custodians, and Facilities. 

What is welding position. Before getting knowledge about the welding position, one must have a look at the types of weld used in welding position. There are two types of weld commonly used in welding position, a Fillet weld, a Groove weld.

Fillet weld is method to join two pieces of metals perpendicularly or at some angle. They are also recognized as the T joint or a Lap joint (Lap joint is when metal piece overlap each other and their edges are welded). The weld is forms in shape of triangle and generally used while connecting Pipes. It is also called a closed weld because the weld metal need not be cut to join.
Groove weld is made in the groove of the metals to be joining. It needs a full penetration to have strong joint. These welds are used for butt edge and corner joints. Groove welds are stronger than fillet welds.

Now, you are familiar with the common types of welds performed in the welding position. Now here comes the question, what are welding positions Welds are categorized according to the positions of the welds during welding.. Basic welding positions are of 4 types which are Flat position, Horizontal position, Vertical position and overhead position. Now let us discuss these positions in details for clarity.

1. Flat position: Flat: It is easiest and convenient type of weld to be performed. Let us suppose that we want to weld two plates. In this position the both plates and the axis of the weld are horizontal. This position is sometimes called down hand. For fillet weld it is named as 1F (1 means the flat position and F means the fillet weld) and for Groove weld it is named as 1G ( 1 means the Flat welding and G means the groove weld). In Flat position gravity draws molten metal downward in joint which makes the joint easy and quick.

2. Horizontal: In this position the plates are vertical and the axis of the weld is horizontal. It is difficult than flat joint because the molten metal flow down to lower plate. It is named as 2G for groove weld( 2 stands for horizontal and G stands for groove weld) and 2F for fillet weld ( 2 stands Horizontal position and F stands for Fillet weld).

3. Vertical: In this position the plates and welds axis both are vertical. Positions are named as 3F ( 3 for Vertical and F for fillet welds) and 3G ( 3 refers as vertical position and G for Groove weld)

4. Overhead: Most difficult and complicated to be performed than the above said positions. It is named as 4G ( 4 means overhead and G for groove weld
And 4F (4 means overhead and F represents Fillet weld). In this position the face of the weld is overhead.

There are three more types of welding positions 5G,6G, 5F
5G welding position is the welding of the pipe in horizontal position that cannot move and is fixed. It is also named as PF in ISO/EN standards. In 5 G welding is done vertically either upwards or downwards. 6 G position is used to weld a pipe joint inclined at an angle of 45 degree. If one clear 6G test, he will automatically qualifies for all the welding position. Welder qualifies with 6G welding position is major concern of the most of the industries. 5 F welding position is for fillet weld. In this position a pipe (in horizontal) and the plate (vertically) are welded. Welder had to make a fillet weld overhead. On passing 5 F test welder passes to weld in all positions. It is very uncommon and not a easy task to perform.

INSULATION

Meaning: 

The fact of being protected from something harmful or the act of covering something to stop heat, sound, or electricity from escapingor entering, or the fact that something is covered
