Procedure for Straightening by Heat Correction method for Structure
Procedure for Straightening by Heat Correction
Thermal techniques
"The basic principle behind the thermal process is to create high local stress so that, on cooling, the job is pulled back into shape. Local heating is a simple and effective process of correcting distortion. This process requires a lot of experience as there is no standard rule of shrinkage so any new job if repair is required then first it should be tested to establish correct shrinkage"

• Root weld end fill in one pass
Application of Ceramic Backing Strip
3metres/minute and produce excellent and accurate bevels. The plates can be beveled, over a range of
6mm to 58mm; and the maximum bevel that can be cut is 28mm. A range of bevellers are available for bevelling different sections of Carbon Steel, Aluminum, Stainless Steel, and Titanium.

WELD AND MAGNETIC FIELD
Effect of Magnetic Field on Welding...
EFFECT ON WELD GEOMETRY
A magnetic field can deflect the arc perpendicular to the welding direction as AC current changes its direction because the direction of electrons changes and this changes the direction of the force on them. This way arc is deflected from the line of a weld. This results in an increase in bead width also.

shrinkage a big factor in welding
How to calculate shrinkage in welding
What is shrinkage?
In a welded joint, expansion and contraction forces act on the weld metal and on the base metal. As the weld metal solidifies and fuses with the base metal, in this stage, it is in its maximum expanded form. While cooling, weld metal contract to the volume it would normally occupy at the room temperature, but it is restricted by the adjacent base metal. Because of this, stresses develop within the weld metal and the adjacent base metal.

HEAT INPUT IN ARC WELDING
ARC ENERGY AND HEAT INPUT IN ARC WELDING
In arc welding process, heat input HI and arc energy AE are measures of how much heat input has been supplied to the job being welded. unit of HI is kj/mm or kj/in. If travel speed is in mm then unit will be kj/mm
arc energy AE = 60VI / 1000s
I = CURRENT IN AMPS
V = VOLTAGE
s = TRAVEL SPEED OF WELDING

INDUSTRIAL PAINTING, CALCULATE PAINT CONSUMPTION
INDUSTRIAL PAINTING, CALCULATE PAINT CONSUMPTION
What is volume solids in painting-
All paints are made up of resign, pigments solvents and adhesive ( like stabilizers, anti-foams, and thickeners). After the paint is applied solvent evaporates and leaving only the dry SOLIDS in the form of a continuous coating. the solid can be expressed as a volume percentage of the entire volume of the can of paint.
example- if a solvent is half of the paint volume then we can say that the paint is 50% solid.
means if the wet film thickness is 100 microns means after drying we shall get 50 microns in thickness.

RAMS and LCC in rail product
RAMS and LCC in rail product manufacturing
All give great importance to this aspect throughout the project in the rail industry, like vehicles and their components. A customer requires reliable products that are easily maintainable throughout its lifetime. The cost of the product in the rail sector is affected by initial cost and also by operating and maintenance costs during its lifetime. All costs are added in the life of LCC from concept to last use of a product.

8D MANAGEMENT TOOL
WHAT IS 8D ( MANAGEMENT TOOL )
THE EIGHT DISCIPLINES (8D)
8 steps to solve any problem in an organization-1: Create a group of people who know the activities and the company.
2: Define the problem.
3: Implement provisionally.
4: Identify the cause. of the incidence.
5: Determine permanent corrective actions (PCAs).
6: Implement permanent corrective actions.
7: Prevent similar problems.
8: Recognize the team’s work. (rewards)
Result: The use of the 8D method allows to improve a product, services, and processes.
---------------------------------
8D क्या होता है?
किसी संगठन में किसी भी समस्या को हल करने के लिए 8 कदम-
1: गतिविधियों और कंपनी को जानने वाले लोगों का एक समूह बनाएँ।
2: समस्या को परिभाषित करें।
3: अनंतिम रूप से लागू करें।
4: कारण की पहचान करें। घटना का।
5: स्थायी सुधारात्मक कार्यों (पीसीए) का निर्धारण करें।
6: स्थायी सुधारात्मक कार्यों को लागू करें।
7: इसी तरह की समस्याओं को रोकें।
8: टीम के काम को पहचानो। (पुरस्कार)
परिणाम: 8D विधि का उपयोग किसी उत्पाद, सेवाओं और प्रक्रियाओं को बेहतर बनाने में मदद देता है।

KPI MUST BE SMART
What makes a KPI effective?
KPI stands for key performance indicator it is valuable as the action it inspires.
for preparing a KPI, a team should start with the basics and understand the organizational objectives,
make a plan to achieve them, and decide who will act on this information. Interact with department heads and take feedback.

HOLI 2021 HOLI KE RANG
HOLI 2021, होली के रंग
HOLI 2021, होली के रंग
फागुन लाया होली संग
फैल गया सबमें उमंग
फूलों के खिलनें से
महक उठा सारा उपवन
रंग बिरंगी तितलियों से
सज गया सारा गुलशन
फूलों से पीकर भंग
गुनगुनाएं भवरे भी संग
हरे पीले नील रंगों से
हुआ आसमाँ का भी इन्द्र धनुषी रंग
आओ बच्चों मिलजुल हम
ऐसी मचाएं होली की हुड़दंग
बन जाएँ सब दोस्त हमारे
रहें न कोई भी दुश्मन
ऐसी कोई छेड़ें सरगम
