04/26 WELDING: metal

WELDING

COALESCENCE:

Liquifying / Coalescence – Melting the workpiece and adding filler material to form a pool of molten material…that cools to become a strong joint, This is in contrast to soldering and brazing which involve melting a lower-melting-point material between the workpieces to form a bond.

PROCESSES

ARC WELDING:

1-SMAW – Shielded Metal Arc Welding – aka “Manual Metal arc welding” or “Stick Welding”

2-GMAW – Gas Metal Arc Welding – aka “MIG” for Metal-Inert-Gas

3-FCAW – Flux Cored Arc Welding

4-GTAW – Gas Tungsten Arc Welding or “Tungsten Inert Gas” – “TIG”

5-SAW – Submerged Arc Welding

GAS WELDING

1-Oxy-Fuel Welding – aka “Oxy-Acetylene” Welding

RESISTANCE WELDING

1-Spot Welding

-film

2-Seam Welding

GEOMETRY

Can be geometrically prepared in a number of ways.  5 basic types:

1-Butt Joint

2-Lap joint

3-Corner Joint

4-Edge Joint

5-T Joint

HARDWARE

Regulator

Torch

Nozzle

Gas

Electrodes

NOMENCLATURE:

“HAZ” Heat Affected Zone

Quality HAZ

Slag

Arc

Penetration

DEFECTS

cracks,

distortion,

gas inclusions (porosity),

non-metallic inclusions,

lack of fusion,

incomplete penetration,

lamellar tearing,

undercutting

SAFETY

Because many common welding procedures involve an open electric arc or flame, the risk of burns and fire is significant; this is why it is classified as a hot work process. To prevent them, welders wear personal protective equipment in the form of heavy leather gloves and protective long sleeve jackets to avoid exposure to extreme heat and flames.

the brightness of the weld area leads to a condition called arc eye in which ultraviolet light causes inflammation of the cornea and can burn the retinas of the eyes. Goggles and welding helmets with dark face plates are worn to prevent this exposure, and in recent years, new helmet models have been produced that feature a face plate that self-darkens upon exposure

FINAL PROJECTS

Take into account how a building’s form is a product of its own technical devices…

Consider the medium specificity of the tools, what do these tools do well?  what dont they do well…?

What is a problem to be addressed?

A Building component:

A project to be reinvented

A problem to be addressed

Demonstrate a precise technological knowledge of what technology to use

REQUIREMENTS:

1 – A categorical taxonomy of research (archive of fabricated projects)

2 – Identification of a problem(try to think of a problematic building process or component)

3 – a working mockup/building component which is the result of the tools and techniques we’ve explored this week…

FOR Monday May 3rd…

1 – redesign your final project

2 – identify a problem

3 – assemble a parts list

4 – Make and present a schedule

4.184 MAKE ARCHITECTURE

4.184 - ARCHITECTURAL DESIGN WORKSHOP:
[MAKING ARCHITECTURE] THE RESULTS
-
Instructor: Nick Gelpi TA: Skylar Tibbits TA: Varvara Toulkeridou
-
Class Times, Monday, 1-4pm - room 5-216
-
4.184 is an intensive introduction to methods of making explored through a wide range of brief but focused 1-week exercises. We'll engage the real and leave behind representation in the focused context of this class gaining skills for utilizing a range of fabrication machines and technologies from lasercutting, waterjet, 3D printing, welding, formworking-molding, casting, gears, joints and composites.
-
In this workshop we'll constrain ourselves to the territory of the 1:1. Students will represent architectural constructions at full scale and develop a more intimate relationship with technology by engaging the tools and techniques that empower us. We will gain access to the most cutting edge machines and technologies in the MARS lab at the Center for Bits and Atoms.
-
The second layer of information for this course will be to look at a series of case studies in which construction methods and technologies have played a dominant role in the design process .
-
Over the past 20 years, architects have focused on the technology of representation to create new ideas of what architecture could be. Looking back today, much of that research failed to substantially change the way we design buildings by focusing on apriori formal configurations. This class makes the contention that this failure comes from a lack of considerations of the potentials within fabrication knowledge. We look to the future of what building might become, given the expanded palette of personalize-able technologies available to us as architects. Students will participate in curious technological and material investigations, to discover the potentials, known and unknown, for these various technologies.
-
The sub-disciplines of what's drawn and what's built have been compartmentalized and disassociated as the representational tools of architecture have distanced themselves from the techniques of making. At the same time the technologies for “making” in architecture have provided us with new possibilities for reinventing how we translate into reality, the immaterial representations of architecture.
